Forced Patinas

[gokusnimbus]

I was googling around for stainless steel patinas and i rain into this thread and how they forced patinas on their knives. i know they're made from hi-carbon steel but im wondering if this would work on mechanical mod steel (304, 316, etc...). 316 is more corrosive resistant but im sure it will eventually give and patina as well.

i wonder if this work on my nemesis?! ive recently battered and bruised it so i think its time to start aging it. like a relic of the past in post-apocalyptic world.

something to this effect:

i dont want to literally rust it but try to recreate the color of rust and pitting.

would this surface treatment affect the conductivity of the mod and cause more voltage drop?

You can "blue" stainless steel with heat .
Can be a tricky affair , but I sis see a website specializing in this , in UK though .

Might be worth looking at motorcycle specialists too .
Having a blued exhaust is pretty popular (on the Japanese sports bikes that is) .

If you want to go DIY , a blow lamp , trial and error , plus something cheap to practice on !

I've done my mod. Incredibly easy to do with a blowtorch.
Got a lovely gold/purple patina by using a mini torch approx 6" from the tube and using a gentle up and down motion.
I practiced for about 10 minutes on some old metal tube beforehand. You soon get a feel for when the metal will change colour.
I used to add patina to silver using 'liver of sulfur' solutions. It never occurred to me to try patinating steel with chemicals. Now i've got to try it.....
